ERNST OESER, OF BERLIN, GERMANY.

PAPER-BOARD MACHINE.

SPECIFICATION forming* part Of Letters Patent NO. 666,207, dated January15, 1 901.

Application filed May 18, 1900. Serial No. 17,128. (No model.)

To all whom it may concern:

Be it known that I, ERNST OESER, manufacturer, a subject of the Emperorof Germany, and a resident of Dresdenstrasse 79, Berlin, in the Kingdomof Prussia and Empire of Germany, have invented certain new and usefulImprovements in Apparatus for Manufacturing Paper-Board, of which thefollowing is a specification.

My invention relates to an improved apparatus for the manufacture ofpaper-board in which a drying-cylinder of large diameter is employed anda series of paste-receptacles and a series of guide-rollers locatedconcentric with and adjacent thereto, so that the continuous series ofwebs or strips of paper are superposed successively on thedryingcylinder as soon as they are pasted, the result being that theseries of webs or strips are passed to the drying-cylinder before theseries of webs or strips has time to absorb the paste and are thusrendered liable to stretch or before the paste has time to dry.

In order that my invention may be fully understood, I will proceed todescribe it with reference to the accompanying drawings, in which-Eigure l is an end elevation of my improved apparatus for manufacturingsix-ply paperboard. Fig. 2 is an end elevation showing modificationthereof.

b is `a drying-cylinder of large diameter turning in the direction ofthe arrow, to which the continuous series of webs or strips of paper care fed from a series of paper-rolls a, around a series of guide-rollersd, contiguous to the drying-cylinder.

In close proximity to and concentric with the drying-cylinder b arelocated a series of paste-receptacles f, in which freely rotate theseries of pasting-rollers f', so that the series of paper webs or stripsc when provided with paste by coming in contact with the series ofpasting-rollers do not have time to stretch, since they come intocontact or union with the next inner web or strip c immediately. Theinner pasted web or strip, however, remains subject to the effect of thedrying-cylinder, and the paste which is applied to the series of webs orstrips has ample time between each two guide-rollers d to dry before thenext web or strip is laid thereagainst.

e designates small guide-rollers, of which there is a series.

The built-up paper-board g is led 0E from the drying-cylinder around anauxiliary drying-cylinder t'. In order to utilize the entire peripheryof the large drying-cylinder, the series of paper webs or strips areintroduced after the manner shown in Eig. 2. The series of rollers daccording to Fig. 2 are arranged in such a manner that they will onlydirect the already-pasted series of webs or strips without pressingthelatter, while the pressing is accomplished by special series ofintermediate pressure-wh, arranged uniformly in rear of the series ofguide-rollers d.

Having thus described my invention, the following is what I claim as newtherein and desire to secure by Letters Patent:

l. An apparatus for manufacturing paperboard comprising adrying-cylinder of large diameter, a series of paper-rolls from which aseries of papel' webs or strips extend to the drying-cylinder, a seriesof paste-receptacles concentric with and adjacent to the dryingcylinder,and having a series of pasting-rollers free to rotate therein, theseries of guiderollers concentric with and adjacent to thedrying-cylinder, and the auxiliary dryingcylinder to which the built-uppaper-board is led.

2. An apparatus for manufacturing paperboard comprising adrying-cylinder of large diameter, a series of paper-rolls from which aseries of paper webs or strips extend to the drying-cylinder, a seriesof paste-receptacles concentric with and adjacent to the dryingcylinder,and having a series of pastingrollers free to rotate therein, the seriesof guide-rollers concentric with and adjacent to the drying-cylinder,the series of pressurerollers concentric with and bearing against thedrying-cylinder, andthe auxiliary drying-cylinder to which the built-uppaperboard is led.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

ERNST OESER.
